Umgaqo
Kwiminyaka yakutshanje, kukho inkxalabo ekhulayo malunga nobungozi bokusingqongileyo kunye nempilo eyenziwa yi-halogen-based flame retardants esetyenziswa kwiiplastiki.Ngenxa yoko, i-non-halogen flame retardants ifumene ukuthandwa ngenxa yeempawu zabo ezikhuselekileyo nezizinzileyo.
I-halogen-free retardants ye-flame retardants isebenza ngokuphazamisa iinkqubo zokutsha ezenzeka xa iiplastiki zibonakaliswe emlilweni.
1.Bafezekisa oku ngokuphazamiseka ngokomzimba nangokwekhemikhali kwiigesi ezinokutsha ezikhutshwe ngexesha lokutsha.Enye yeendlela eziqhelekileyo kukuqulunqwa komgangatho wekhabhoni okhuselayo kumphezulu weplastiki.
2. Xa zibonakaliswe kubushushu, i-halogen-free flame retardants ifumana i-chemical reaction, ekhupha amanzi okanye ezinye iigesi ezingatshayo.Ezi gesi zenza umqobo phakathi kweplastiki kunye nedangatye, ngaloo ndlela inciphisa ukusasazeka komlilo.
3. I-halogen-free flame retardants ibola kwaye yenze i-stable carbonized layer, eyaziwa ngokuba yi-char, esebenza njengesithintelo somzimba, ukukhusela ukukhululwa okuqhubekayo kweegesi ezinokutsha.
4. Ngaphezu koko, i-halogen-free flame retardants inokunciphisa iigesi ezivuthayo nge-ionizing kunye nokubamba i-radicals yamahhala kunye nezixhobo ezivuthayo ezinokutsha.Le ndlela yokusabela yophula ngempumelelo ikhonkco lokutsha, inciphisa ngakumbi ubunzulu bomlilo.
I-Ammonium polyphosphate yi-phosphorus-nitrogen halogen-free flame retardant.Inomsebenzi ophezulu wokubuyiswa komlilo kwiiplastiki ezingenayo ityhefu kunye nokusingqongileyo.
Isicelo sePlastiki
Iiplastiki ze-flame retardant ezifana ne-FR PP, i-FR PE, i-FR PA, i-FR PET, i-FR PBT kunye nokunye zisetyenziswa ngokuqhelekileyo kwishishini lemoto kwi-interiors yemoto, njenge-dashboards, iipaneli zomnyango, izihlalo zokuhlala, i-enclosures zombane, i-cable trays, ukumelana nomlilo. iiphaneli zombane, izixhobo zokutshintsha, iindawo ezivaliweyo zombane, kunye nokuthuthwa kwamanzi, imibhobho yegesi
umgangatho wokubuyiswa komlilo (UL94)
I-UL 94 ngumgangatho wokutsha weplastiki okhutshwe yi-Underwriters Laboratories (USA).Umgangatho uhlela iiplastiki ngokwendlela ezitshisa ngayo kwiindlela ezahlukeneyo kunye nobukhulu becala ukusuka kweyona nto iphantsi kwedangatye ukuya kwi-flame-retardant kwiindidi ezintandathu ezahlukeneyo.
| Ireyithingi ye-UL 94 | Inkcazo yoHlelo |
| V-2 | Ukutshisa kuyayeka kwimizuzwana engama-30 kwindawo evumela amathontsi eplastiki enokutsha ethe nkqo. |
| V-1 | Ukutshisa kuyayeka kwimizuzwana engama-30 kwindawo ethe nkqo evumela amathontsi eplastiki angadumbanga. |
| V-0 | Ukutshisa kuyeka kwimizuzwana eyi-10 kwindawo ethe nkqo evumela amathontsi eplastiki angavuthi. |
